    QoS through ACL? ShoreTel Voice

    jgard New Member

      Hello All,

       

      I've successfully applied QoS on my Adtran, and it's marking the packets correctly. However, i'm still seeing some voice quality issues at the remote locations. Below is what I have applied, but came across someones post suggesting I create an ACL and doing the following:

      access-list 105 remark : ShoreTel VoIP Call Control and CSIS

      access-list 105 permit udp any any range 5440 5448

      access-list 105 permit udp any any eq 2427

      access-list 105 permit udp any any eq 2727

      access-list 105 permit tcp any any eq sunrpc

      access-list 105 permit udp any any eq sunrpc

      access-list 105 permit tcp any any eq 5440


      I'm not really familiar with creating and marking through ACL's. Could someone please help me out?

          jgard - Thanks for posting your question on the forum!

           

          With the configuration you provided, QoS is currently setup to match traffic marked with a DSCP value of 46. This is the DSCP value most voice packets from IP phones are marked with. This traffic would then be given priority of 1 Mbps should the link become congested.

           

          I would be more than happy to help you configure the ACL in your QoS map, however, I am a little unclear if you would like to mark the traffic in your ACL with a certain DSCP or precedence value or if you would just like to prioritize this traffic?

           

          Please do not hesitate to let us know if you have any questions.

           

          Thanks,

          Noor

            Depending on what version ShoreTel you are using may change your QOS needs.

             

            You can set RTP DSCP for shore Gears and phones only on pre 13.x code.  What that means, only set to
            set or Shore gear RTP is prioritized no signaling and no Call server RTP.

             

            13.x and later you can set the call server RTP and signaling
            DSCP.

             

            If you run “sho qos map int ppp 1”  do you see matches?

             

            I sometimes do this to set dscp on input interface:

             

            qos map remark 10

            match ip list 105

            set precedence 46

             

            interface eth 0/1.1

            vlan-id 1 native

            no shutdown

            ip address 10.7.51.1 255.255.255.0
